.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is turned on, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

way too many mistakes in technical documents.
"NAME"
SSL_CTX_add_extra_chain_cert - add certificate to chain
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/ssl.h> \& long SSL_CTX_add_extra_chain_cert(SSL_CTX ctx, X509 *x509) .Ve
"DESCRIPTION"
Header "DESCRIPTION" \fISSL_CTX_add_extra_chain_cert() adds the certificate x509 to the certificate chain presented together with the certificate. Several certificates can be added one after the other.
"NOTES"
Header "NOTES" When constructing the certificate chain, the chain will be formed from these certificates explicitly specified. If no chain is specified, the library will try to complete the chain from the available \s-1CA\s0 certificates in the trusted \s-1CA\s0 storage, see \fISSL_CTX_load_verify_locations\|(3).

The x509 certificate provided to SSL_CTX_add_extra_chain_cert() will be freed by the library when the \s-1SSL_CTX\s0 is destroyed. An application should not free the x509 object.

"RESTRICTIONS"
Header "RESTRICTIONS" Only one set of extra chain certificates can be specified per \s-1SSL_CTX\s0 structure. Different chains for different certificates (for example if both \s-1RSA\s0 and \s-1DSA\s0 certificates are specified by the same server) or different \s-1SSL\s0 structures with the same parent \s-1SSL_CTX\s0 cannot be specified using this function.
"RETURN VALUES"
Header "RETURN VALUES" \fISSL_CTX_add_extra_chain_cert() returns 1 on success. Check out the error stack to find out the reason for failure otherwise.
"SEE ALSO"
Header "SEE ALSO" \fIssl\|(3), \fISSL_CTX_use_certificate\|(3), \fISSL_CTX_set_client_cert_cb\|(3), \fISSL_CTX_load_verify_locations\|(3)
